Not to be confused with Inconel, Incoloy lap joint flanges are made of a nickel alloy which contains iron and a lower content of nickel. Incoloy is essentially a more economical option to Inconel, yet with more restricted corrosion resistance and temperature limits. Typically, Incoloy is an ideal material for long-term exposure in high temperature environments due to its oxidation, carburization and creep resistance. Incoloy is widely used for its resistance to seawater, brine, sour gas and high chloride environments at elevated temperatures, which make it a popular choice in the oil and gas and power industries.
The most commonly used grades of Incoloy flanges are Incoloy 800, 800H, 800HT;Incoloy 825; and Incoloy 925. For more indepth information on these specific grades, visit our specific web pages or contact one of our engineering experts:

Frequently Asked Questions
Q: What is a slip on flange incoloy used for?
A: This flange is used to connect piping, valves, and equipment in corrosive, high-temperature service where weldability and alignment are important. Incoloy slip on flanges suit petrochemical, furnace, heat exchanger, offshore, and sour-gas systems. Grades such as 800/800H/800HT retain strength during prolonged heat exposure, while 825 improves resistance to chloride, sulfuric, and phosphoric media. The slip-on design allows easy fit-up before fillet welding.
Q: What materials are available for slip on flange incoloy?
A: Available materials include Incoloy nickel-iron-chromium alloys 800, 800H, and 800HT for elevated-temperature strength and structural stability. Incoloy 825 adds molybdenum and copper for improved corrosion resistance in acidic and chloride-containing environments. Incoloy 925 is a precipitation-hardened alloy offering higher mechanical strength. Material supply can be certified with EN 10204 3.1 MTC for traceability and compliance in critical industrial applications.
Q: What pressure ratings does a slip on flange incoloy support?
A: Pressure ratings are not fixed in the provided specification and are typically supplied to the required ASME flange class and dimensional standard. Actual pressure capability depends on alloy grade, flange dimensions, service temperature, and applicable code calculations. For high-temperature duty, grades 800H and 800HT are preferred because they maintain strength better during prolonged exposure. SASA FLANGE can quote the correct class based on design conditions.
Q: What standards does a slip on flange incoloy comply with?
A: These flanges can be manufactured and certified to ASTM B408, ASME SB408, ASTM B564, ASME SB564, EN 10204-3.1, BS 3076NA16, ASTM B425, ASME SB425, ASME Code Case N-572, DIN 17752, DIN 17753, DIN 17754, VdTÜV 432, ISO 9723, ISO 9724, ISO 9725, ASTM B637, and NACE MR0175. This supports material integrity, dimensional control, and sour-service suitability where required.
Q: What is the lead time for custom slip on flange incoloy orders?
A: Custom orders for Incoloy slip on flanges typically require 15-30 days, depending on alloy grade, size, quantity, and testing scope. Standard stock items are usually available in 3-7 days.
